I am trying to help someone who asked me for input on a Princess Cruise Tour. I am very familiar with the Natural History Tour", "Tundra Wilderness Tour", etc. and the difference between the tours and shuttles. I have never before heard of the following, and I quote: "This morning, take an educational tour into Denali National Park. " Does anyone have any experience with this tour or know anything about it? Since some of Princess' offerings state the "Natural History Tour" I am guessing this is something different. Any ideas/thoughts/knowledge? Thanks so much!!!
